DIMETHYLIMIDAZOLIDINONE CORN STARCH.

Valuable CAS 223239-90-5 / ABSORBENT, VISCOSITY CONTROLLING

Dimethylimidazolidinone Corn Starch is a modified corn starch derivative prized for its multi-functional benefits in cosmetic formulations. It acts as an effective absorbent and texture modifier, crucial for enhancing product feel and performance.

Summary

Absorbent Texture enhancer Mattifying agent Anti-tack agent Binding agent

Science

Mechanism of Action

This modified starch functions primarily by leveraging the natural absorbent capacity of corn starch, which comprises amylose and amylopectin. These carbohydrate polymers are capable of swelling and forming extensive networks, enabling them to efficiently absorb excess oil and moisture from the skin's surface. This mechanism contributes to a discernible mattifying effect, significantly reduces product tackiness and greasiness, and ultimately improves the spreadability and overall sensorial experience of skincare formulations.

Stability

While general corn starch is insoluble in cold water and organic solvents, it can form dispersions that become soluble in water at its gelatinization temperature, and is miscible with water upon swelling, particularly in hot water. Starch glycosidic bonds exhibit stability in alkaline environments but are prone to acid or base hydrolysis, especially under elevated temperatures. A related ingredient, Dimethylimidazolidinone Rice Starch, has a pH noted at 5.5, which is generally compatible with skin's natural pH.

Conflicts

  • Ketoconazole (in pharmaceutical contexts for general corn starch)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

Specific safety assessments by bodies like the CIR Expert Panel or SCCS for Dimethylimidazolidinone Corn Starch have not been identified. However, the CIR Expert Panel has generally affirmed the safety of corn-derived ingredients for cosmetic use within established practices and concentrations. The FDA's delisting of 'Cornstarch' pertains solely to its use as a color additive, not as a functional ingredient. Furthermore, a similar compound, Dimethylimidazolidinone Rice Starch, is not currently listed on EWG's restricted or unacceptable lists, suggesting a generally favorable safety profile for this class of modified starches.
